Hi bluetrain,
I have updated the code in the templates/ja_stark/html/com_content/article/default.php file, line 63:
Replace this:
<?php if ($this->item->publish_down && (strtotime($this->item->publish_down) < strtotime(Factory::getDate())) && $this->item->publish_down != Factory::getDbo()->getNullDate()) : ?>
<span class="badge badge-warning"><?php echo Text::_('JEXPIRED'); ?></span>
<?php endif; ?>
With this code:
<?php
$timePublishDown = $this->item->publish_down != null
? strtotime($this->item->publish_down) : '';
if ($this->item->publish_down && ($timePublishDown < strtotime(Factory::getDate())) && $this->item->publish_down != Factory::getDbo()->getNullDate()) : ?>
<span class="badge badge-warning"><?php echo Text::_('JEXPIRED'); ?></span>
<?php endif; ?>
